A
threat to life as we know it…

There are certain conditions that allow for
life to flourish on Earth. One of these conditions is that it is neither too
hot nor too cold for all living things. It’s just right – and we easily adapt
to it. In the past, there were changes in the Earth’s temperature that caused
the planet to become too cold - this is the time of the Ice Age. These
temperature changes were only a few degrees lower, but many species were unable
to cope and they went extinct.

What’s
the Earth’s Temperature?

You hear about Global Warming and how many
people are concerned that it is being caused by humans and human activity – and
that it is threatening our very existence. Scientists are now 97% sure that it
is true. With all the fossil fuel that we burn, there is definitely more carbon
dioxide in the atmosphere now as compared to the past. We use up so much energy
and the continued increase in population can only mean that we will need and
use more energy in the future. This means more carbon dioxide and methane
emissions which contribute to the warming of the planet.

The planet is now 1 degree Fahrenheit
warmer than it was back in the 1800’s. Much of the increase in temperature
happened in the last 30 years. Can you imagine how much heat is required to
warm the whole planet even by 1 degree?

The
Greenhouse Effect

Our atmosphere is responsible for keeping
the Earth’s temperature stable. It is made up of layers of gases such as Water Vapor,
Carbon Dioxide, Methane, Nitrous Oxide and Ozone.

When the sun’s rays warm the Earth, the
Earth reflects the heat back into space. Some of this heat is trapped by the
gases in our atmosphere, keeping the planet comfortably warm for everyone and
the weather stable.

When we upset the balance of the gases in
our atmosphere, problems will happen. Right now, we are adding more carbon
dioxide and methane because of our activities. The result of these additional
gases is more heat gets trapped on Earth, causing Global Warming.

The
problem with Global Warming

So, what’s the problem if the Earth becomes
too warm? A lot of things that are not good for living things, including us.

For starters, the weather will change. Warm
places will become colder and cold places will be warmer. The storms and
hurricanes that we see from time to time will be stronger and more destructive,
as the ocean temperatures increase too.

In some places, there will be less
rainfall. Crops will be more difficult to grow as water becomes scarce. As
water becomes scarce, food will also be harder to come by and there will be
famine and hunger.

Then, the glaciers and the polar ice caps
will melt, causing the sea levels to rise. Remember that most of the major cities are
near the coastline. If the sea levels rise by 6 feet, most of them will go
under the water – destroying buildings and houses and killing off millions of
people, plants and animals.

Global Warming is a scary thought, but
there is still something we can do now to stop the planet from getting warmer. If we don’t act now, our future generation
will be the ones to suffer the consequences of our actions.
